The Computation of Azimuth and the Shortest Path between Two Points on the Earth's Surface

Abstract:

In this paper, first, analytic geometry are used to calculate the normal transversal azimuth on the ellipsoid surface, then modification value is calculated to get a more accurate orientation angle. Second, based on geodesic differential equations, segmented cumulation for distance between two points on the ground is brought forward. Each section is a short distance, so the result is more accurate. Moreover, when applyed to the program, angle is all got by anti cotangent function, thus avoiding to cumbersomely judge the quadrant.
